Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed January 13, 1919. Serial No. 270,960.

To all whom it may concern:

Be it known that I, WILLIAM 0. PAGE, a citizen of the United States, residing at Tueson, in the county of Pima and State of Arizona, have invented certain new and useful Improvements in V alive-Removers, of which the following is a specification.

This invention relates to wrenches, and more especially those which are inserted in the object turned; and the purpose of the same is to produce a tool for insertion mto the valve insides of a Schrader tube nipple for removing the same when desired.

With this object in View, the invention consists in a javelin of peculiar external configuration, channeled along one side for a purpose yet to appear.

In the drawings- Figure 1 is a sectional view through a complete Schrader valve, showing the tool in use Fig. 2 is a perspective view of the tool or wrench on an enlarged scale.

The construction of the Schrader valve is well known. In the drawings the letter N designates the nipple and I the valve insides as a whole. We are concerned only with the threads 1 at the outer end of the nipple, the tubular plug 2 which screws into them when the insides of the valve are inserted, and the rod which extends loosely through this plug and is flattened as at 3. My improved tool, best seen in Fig. 2 is a javelin made of a stout piece of wire having a straight round body indicated at 4, a handle 5 at its outer or upper end, which handle may take any appropriate form but is herein shown as a right-angular bend, and a pointed or reduced lower end 6. This end is channeled along one side as at 7 for more than half the thickness of the body 4, the channel running out at an appropriate point 8, but the other or outer side of the end 6 follows the contour of the body. The channel may be cut on an angle or a curve, and if the latter, then the cross section of the pointed end of the tool or implement would be of crescent shape.

In the use of this device, the tool is inserted into the outer end of the nipple N as seen in Fig. 1, its channel receiving the wire and being of appropriate depth to receive the flattened portion 3 thereof. The rounded side of its pointed end 6 faces outward if we assume that the wire stands along the center of the bore through the tubular plug 2, and the extreme point of the tool passes 1nto said bore and is pushed down into the same until it reaches the position shown in Fig. l or when it wedges in place therein and firmly grips the plug without having deflected the wire to an undue extent. Now by rotating the tool by means of its handle, a plug may be turned within the threads 1 and withdrawn from the mouth of the nipple, and therefore, the entire valve insides can be readily removed. I find this tool more useful than the ordinary implement employed for withdrawing the insides, and its utility is probably due to the fact that in pushing the point of the tool into place, the wire is to a slight extent deflected from its axial position, with the result that the valve on the wire is pressed away from or out of adhesive contact with its seat; and thereafter, the rotary movement of the body 4 of the tool which turn the plug is not resisted by the sticking of the valve, and in fact, the movement of the tool turns the wire and probably the valve itself. In any event, I have been able to remove the insides with this tool where they could not be removed with anything else.

The foregoing description and the drawings have reference to what may be consid ered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is As a new article of manufacture, a valve remover formed from a strand of comparatively heavy cylindrical material forming a body, said body being bent contiguous to one end to form an angularly extending In testimony whereof I alfix my signature handle, said body being tapered ad acent in presence of two witnesses.
